Also check out the openssl plugin. All you need is Vim and openssl on your system and you can be editing encrypted files right now! Files can be encrypted with most ciphers supported by openssl: aes, blowfish, des3, etc. The cool part is that the plugin transparently handles decryption when you open a file and encrypting it again before you write it. Just do your typical ":wq" and it will ask you for an encryption password before it writes. ... It also has a password safe feature. Now you don't need to install a separate password safe and your password file is encrypted with standard OpenSSL supported ciphers that can later be decrypted with just `openssl` alone -- the original openssl.vim VimScript is not required for decryption. --Noahspurrier 01:30, 26 November 2008 (UTC)

which works just fine, and uses a single command (which is almost certainly installed already).

Also, use of an alias for cvim might be more suitable than use of a shell script, since the arguments all come at the end of the line anyways. This won't require installing a script as root either; it's probably better for a user that wants to do this to just add the alias to their .bashrc/.bash_profile.
